REPAIRING 0R ASSEMBLING METAL POLES.

Application lccl May 12, 1922.

To all whom t may concern Be it known that I, lVAL'rnR J. QU'INN, acitizen ot the United States, and a resident of the city, county, andState of New York, have inventedcertain new and useful Improvements 'inRepairing or Assembling Metal Poles, o1 which the following is aspecification.

My invention relates in general to the construction or" hollow metalpoles, and more particularly to the provision oi a repair section whichcan be readily applied to reinforce or replace a worn or weakenedportion of the pole. It will., however, be apparent from the descriptionof the invention that its features are adapted to be used in assemblinghollow metal poles in the original construction of same or when they arebeing installed for service.

The broad principle involved in the invention resides in the provisionof a section or unit adapted to slip over the part to which it is to beconnected, such section or unit having a more or less closely iittingneck portion which is slotted lengthwise to provide for slight variationin diameter but integral with or united to a base portion so that theentire unit is, in eifect, a one-piece unit. After this unit has beenslipped over the part to which it is to be united, the two are weldedtogether along the slot whereby the neck portion shrinks slightly incooling and the two parts are rigidly secured together.'

To clearly illustrate my invention, I shall describe the samel withreference to the accompanying drawing in which- Figure 1 represents atubular steel pole set in the ground, with the repair unit appliedthereto.

Figure 2 is a vertical section of a portion thereof on the line 2-2 ofFigure 1.

Figure 3 is a transverse section thereof on the line 3-3 oi Figure 2,and Y Figures 4, 5 and 6 are detail perspective views of threealternative constructions of the repair unit differing, however, only inthe number of slots formed in the neck portion.

Referring in detail to said drawing, the pole illustrated in Figure 1 issuch as commonly employed, for example, in supporting the over-headconductors oi electric street railway systems and Iy have illustratedthis pole as comprising sections 10, 11 and 12 united together in theordinary way and Serial No. 560,418.

provided with the repair unit 13 which has the neck portion 14 somewhatreduced in diameter from the main base portion of the repair unit andslotted at 15. The neck portion 14 tits snugly but yieldingly over thetubular unit 1Q and after it has been placed thereon its slot 15 isl'illed with welding metal which has the effect of drawing the neckportion tightly against the tubular unit 12 and uniting the two memberstogether. A line ol' welding metal 16 may be applied over the top of theneck 14 to eX- clude moisture, which would be detrimental.

Referring to Figure 2, the repair unit is shown applied over what I mayrefer to as a typical example of a deteriorated pole such as occurs inthe supports i'or the overhead wires o'f street railway systems. Herethe lower-most section 17 of the original pole is illustrated as havingbeen eroded or worn away just above the ground level until it is readyto tall. common and special devices have been gotten up for makingrepairs in such situations. According to my invention, this repair isreadily made in the field or, in other words, without the necessity oftransporting the pole to the home shop for repair. The lower portion ofthe worn-out section may be sawed oli' and the repair unit 14 slippedover the remaining lower end of the pole by excavating or by raising thepole, or the wires may be temporarily supported and the end of the poleswung out to permit the repair unit to be slipped over the lower end ofthe pole without the necessity oi removing the part below the wornplace. It is also possible to apply the repair unit by disconnecting thecross arms at the top oi the pole and slipping the repair unit over thepole from above until it has been brought down to the position in whichit is to be secured.

It is obviously permissible to construct the repair unit with one or aplurality of longitudinal slots such as 15. Figures 4, 5 and 6 showrespectively one, two and three slots and it will be understood thateach of these will be filled with welding metal after the repair unithas been placed in position on the pole. The base portion by which theslotted neck is maintained integral in the examples shown is ot'somewhat larger diameter so as to provide clearance and renderunnecessarv the slotting of the base portion to prevent sticking orjamming which This occurrence is quite might otherwise-- occur inapplying the repair unit to the pole. The invention, however, is notlimited in its broader aspects to the base portion being of 'greaterdiameter than the neck portion although I do prefer, as a specificfeature of 4the invention, to employ this construction. The inventionis, however, limited to the repair unit being' so constructed as to bein effect a unitary structure so as to render unnecessary the use ot ybe transported .by conveyances unsuitable to carry the completedpole4conveniently. 'ln such cases', the pole may' be conveyed in convenientlengthsa'nd when being installed. these lengths can'be readily joined byuse ot the unit Which forms the subject ot this invention. p The basesection of the unit may, for example, be constructed so as to serve asthe, ultimate base of `the pole or it may tit-'Within or over a loivervsection and be united thereto. Where it lits over a loiver section itsconstruction may obviously be similar to that olz the neck portion Whereslots are provided toenable it vto vary somewhat in diameter to properlyconform with the diameter of the part over which it is fitted. Weldingmay then be applied as already described.
